(a) Contour plots showing scattering and absorption cross-section efficiency calculated using Mie theory for spheres of Au, Ag and Al (all plots use an identical logarithmic scale bar). (b) a schematic diagram of the p-n junction photodiodes with an array of nanocylinders on the front surface (the composition, thickness and doping density of each layer is indicated on the diagram), and (c) SEM image of a periodic array of Al nanocylinders fabricated by electron beam lithography (scale bar is 500 nm).
